Title:     Searching for Dark Matter with the XENON1T Detector

Abstract: Astrophysical observations at many scales provide indisputable evidence for the existence of an invisible and dominant mass component in the observable universe. Understanding the nature of this so-called dark matter remains one of the greatest challenges of modern physics. The leading hypothesis is that dark matter is made of new elementary particles, with a vast range of potential masses and interaction cross-sections with normal matter. A well-motivated class of candidates are Weakly Interacting Massive Particles (WIMPs). One way to search for WIMPs is through their scattering off atomic nuclei in low background detectors placed deep underground. I will present the XENON1T dark matter experiment ongoing at the Italian Gran Sasso Laboratory, the first to deploy multiple tonnes of liquid xenon as the target and detector material. The first search with XENON1T has demonstrated an unprecedented low background and the best sensitivity over a wide range of WIMP masses.

Stimulants available 15 minutes before the talk.
